Report lists a PkgImage's "external methods" belonging to its own module

[NHDaly]

(EDIT: Oops, sorry, I accidentally hit shift-enter while editing the title.)

In the following report, PkgCacheInspector shows my 16% of the external methods for my package, MuttsDicts, as belonging to itself. But in that case, aren't they not external?

Something seems either broken or confusing here. Thanks!
